|What registry keys/files affect USB under windows XP? I know that USB runs at 5V but when the computer goes into sleep, standby etc I hear that the OS determines what mode the USB port is in and how much voltage to feed it? Everything i've found so far points me that USB is not controlled by hardware such as a motherboard.|
Basically, I have a USB device thats having problems when the computer starts. It wont initialize on startup. But if I remove the device, then re insert it, it acts normally. Im trying to figure out what is causing this. (and why when i re plug it in it refreshes and works then, but not before) Gets hung on initializing device and hangs. Does not lock up system just sits there and looks at me. But when I remove it plug it back in it initializes fine.
Im getting a voltmeter later today im going to put it on the pins and startup the computer see what changes while its booting.
Are there any files or registry keys within the operating system of XP that someone can alter values or change. Anything. Anything at all, any settings that have to do with USB.
Im pretty sure that when the computer boots the device is in low power mode. But when I re plug it back in it switches to high power mode. Im trying to figure out how to make this more stable.
